If you go to Jenny's deviant art page http://www.ashwings.deviantart.com/ she has some good tutorials on using photoshop and you can google webcomic design and find awesome pointers from people who've made webcomics of their own.

Stan and Gray Wolf, I'd actually recommend the Writing Excuses podcasts if you're interested in pursuing writing. I can't remember the URL (probably writingexcuses.com or something) but we have a link to it in the links section.
